For split keyboards using `LED_MATRIX_SPLIT` with an LED driver, you can either have the same driver address or different driver addresses. If using different addresses, use `DRIVER_ADDR_1` for one and `DRIVER_ADDR_2` for the other one. Then, in `g_is31_leds`, fill out the correct driver index (0 or 1). If using one address, use `DRIVER_ADDR_1` for both, and use index 0 for `g_is31_leds`.

As mentioned earlier, the center of the keyboard by default is expected to be `{ 112, 32 }`, but this can be changed if you want to more accurately calculate the LED's physical `{ x, y }` positions. Keyboard designers can implement `#define LED_MATRIX_CENTER { 112, 32 }` in their config.h file with the new center point of the keyboard, or where they want it to be allowing more possibilities for the `{ x, y }` values. Do note that the maximum value for x or y is 255, and the recommended maximum is 224 as this gives animations runoff room before they reset.
